Microsoft released Windows Defender Beta 2 today and is available for public download. The feature set seems to be put together quite well. For those of you running 64-bit systems you will be pleased to know that you can download the 64-bit of Windows Defender to test. They redesigned the interface to make it easier to understand and more intuitive for users. I haven’t been using it very long, but it seems to be very well cleaned up when compared to the Microsoft AntiSpyware. Give it a shot, it’s free!
